Corrugated tube expansion joints are single or multi-layer stainless steel expansion joints with higher expansion absorption and lower spring rates. Corrugated tube expansion joints are used e.g. in exhaust, district heating and blast furnace pipe work, in mechanical, appendix and apparatus engineering as well as in industrial or sprinkler installations.

Corrugated tube expansion joints are stainless steel corrugation designed contributing to the solution of piping system problems. It is used to absorb pipe movements, relieve stress, reduce system noise/vibration, compensate for misalignment/offset and protect rotating mechanical equipment against start-up surge forces. Assemblies are designed for both high and low temperatures.

It is made of SUS304 material, multiply  bellows with features of lower elasticity coefficient, high-temperature and high-pressure resisiting, applied to absorb the expansion or copression of the HTM fluid pipeline. It can make a long service life in piping system.

Kosga has over 40 years design experience in manufacturing the industrial pipe fittings, such as the rubber expansion joint, metal expansion joint, dismantling joints, pipe valves, etc. 

All the metal expansion joints comfirm with the international standards, such as GB, ISO, DIN, ANSI, BS, JIS, as well as customers'special demand.

Main Advantages:
·Compensate misalignment, absorbs vibrations in the pipeline
·Directional Movement Absorbing
·Wide Size and Service Range
·For both high and low temperatures
·Materials available upon request
